DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching device, and more particularly to a punching device suitable for punching a plurality of pieces (pieces) from a workpiece such as a ceramic green sheet or a printed circuit board in a later process. It is.

[0002]

2. Description of the Related Art Heretofore, a punching unit of this type has a punching unit 1 having a punch and a die facing the punch.
Comprising a body or a plurality thereof in a row in the X direction,
Generally, hunting is performed while gripping and moving the work in the X and Y directions.

[0003]

In such a drilling device, it is necessary to drill a hole to be drilled while moving the workpiece to be drilled from the movement start end to the movement end in the moving part even in the hole having the same shape. For example, even when a large number of plate materials are taken in a post-process from a work such as a ceramic green sheet or a printed circuit board, a punching motion is carried out while moving each plate material at every time by a moving unit, and a hole having the same shape is obtained. Is perforated.

SUMMARY OF THE INVENTION The present invention has been made in view of the conventional circumstances, and a purpose thereof is to provide a drilling apparatus which is most suitable for drilling holes of the same shape at the same position on a plate material which is to be taken out from a work. Is to provide.

[0005]

Means for solving the problems The technical means taken to achieve the above-mentioned object is to hold a punch with a moving portion movable in the X and Y directions and move the workpiece while facing the punch and the punch. In a punching device for punching with a punching unit provided with a die, a plurality of punching units parallel to the X direction are connected to each other by a parallel interval adjusting means, and among the punching units, a reference punching unit is moved from a reference point. When a centering detection unit for teaching for detecting the center of a desired mark of a work is fixedly provided at a predetermined interval, and the centering detection unit detects the center position of a desired mark of the work during operation, The moving unit is controlled to move the punch so that the mark is located immediately below the punch of the punching unit serving as the reference. And summarized in that in communication with the control unit for Dado on.

According to the above technical means, the parallel spacing adjusting means sets the plurality of punching units in the X direction at the same interval, that is, the pitch interval of the punching marks at the same position on the plate material taken out from the workpiece. Keep it. So
And a large number of workpieces are
The centering detector detects the perforated mark with the plate material
Detecting and teaching, and centering detector during operation
When the controller detects the center position of the perforated mark,
Move the punch mark to just below the punch and punch
And a hole of the same shape at the same position on the plate
Drilling can be performed simultaneously without moving .

Is pressed against the upper surface of the base 12 so that each punching unit 1 can be immovably fixed at the interval adjustment position.

Reference numeral 82 denotes fine adjustment means for adjusting the interval between the punching units in the Y direction. The fine adjustment means 82 in the Y direction is provided with a compression spring interposed between the rear side of the protrusion 72b and the inner surface of the corresponding large hole 72a of the plate 32.
82a and a spindle 82b 'attached to a protruding piece 51 vertically extending from the lower end of the rear surface of each punching unit 1,
The micrometer head 82b abuts on the rear surface of the micrometer head 82b. The fixing portion 72 is loosened and the knob 82b "of the micrometer head 82b is rotated to operate the Y linear guide 42 via the compression spring 82a. , 42, each punching unit 1 can be finely adjusted in the Y direction by being pushed (FIGS. 2, 3).

The first punching unit 1a serving as a reference is provided with a centering detection unit for teaching for detecting a desired mark 100 'of the work 100 moved from a reference point (an origin through which the work is gripped and moved). 61 is fixedly provided.

This centering detecting section 61 is a CCD camera 61
a, an image processing device (not shown) that communicates with the CCD camera 61a.
Move the mark 100 ′ while moving it in the Y direction
a, the reflected image is binarized by an image processing device, and the binarized image is searched on a monitor screen to detect the center.
Teaching to a control unit (not shown) with 100 'centered.

The control unit calculates the moving distances in the X and Y directions required to move the desired mark 100 ′, which has been taught at the center detected by the centering detecting unit 61, to just below the punch 21. When the mark 100 'moves to a position just below the punch 21 of the reference punching unit (first punching unit 1a) 1 by the control operation of the moving unit 3 based on the calculation result, all the punching units 1, 1a, 1
The punches 21 of b, 1c are driven together. Although not shown, the centering detection unit 61 may be an offset microscope.

Next, the operation of the present embodiment will be described.
As shown in FIG. 1, when six plate members 102 are taken from a work 100 such as a ceramic green sheet or a printed circuit board in a post-process (three rows and two columns), the parallel spacing adjusting means 2 in the X direction is used. , The center of the punch 21 of the punching unit (first punching unit 1a) 1 serving as a reference so as to match the mark pitch interval of the same position of the plate 102 in each row, and the second position. Center of punch 21 of punching unit 1b and third punching unit 1c
Adjust the distance between the centers of the punches 21. Then, a test drill is performed using a work for practice, the drill interval is measured using a measuring instrument, and the measurement error is finely adjusted by the micrometer heads 52e and 82b. Then, the center of the mark 100 'to be punched on the outermost (left side in FIG. 1) plate material 102 in the actual pre-drilling operation is stored in the control unit by teaching.
The mark 100 'is moved via the moving unit 3 directly below the punch 21 of the punching unit (first punching unit 1a) 1 serving as a reference, and the center of the mark 100' is punched. ... holes of the same shape can be simultaneously opened at the same position.

In FIG. 1, the remaining horizontal row of plate members 10
The center of the mark 100 ′ to be pierced on the outermost (left side in FIG. 1) plate material 102 is also stored in the control unit by teaching each time, so that the punching unit with the mark 100 ′ as a reference (First
At the same time as the perforation is performed immediately below the punch 21 of the punching unit 1a) 1, the other two plate members 102 can be simultaneously perforated at the same position in the same shape.

In this embodiment, a punching apparatus having a number of punching units 1... Arranged in the same number as the number of rows of the obtained plate members 102 is described. The present invention is also applicable to a punching device in which the units 1 are juxtaposed, a punching device in which about a number of punching units are juxtaposed to the obtained plate material, and the like. In these cases, the center of the mark to be pierced on the outermost (left) plate material is stored in the control unit by teaching for each plate material group punched by the punching unit group. After the holes having the same shape are punched, a program control may be performed in which adjacent plate members are sequentially punched by the same punching unit group.

Also, since the punches can be exchanged and the distance between the punching units in the X direction can be adjusted,
It is also possible to make holes of different types together in the plate.

As described above, the present invention has the following advantages. Grasping with a moving part that can move in the X and Y directions
